What should I do if the condition for php to operate MYSQL is more, better or less?

If you want to update sql1 & quot; updatetablesetaaaawhereid1 & quot; sql2 & quot; updatetablesetaaaawhereid1andclassid12andinfoid1 & quot ;; if delet php is used to operate MYSQL statements, the more the statements, the better, the less the statements, the better.
Ask
If you want to update
Sql1 = "update table set aa = aa where id = 1 ";
Sql2 = "update table set aa = aa where id = 1 and classid = 12 and infoid = 1 ";

Delete:
Sql1 = "delete from table where id = 1 ";
Sql2 = "delete from table where id = 1 and classid = 12 and infoid = 1 ";


Which of the following is better for SQL 1 and SQL 2 during update?
Which of the following is better for sql1 and sql2 during delete?

So you don't need to ask this question... it's obvious that the old man (Mysql) can filter it out for you.

In many cases, failing to write the conditions is counterproductive.

2. let me talk to the old man, who is 170 tall and 80 in the upper circle. call the lady who meets these conditions, and then find a lady who meets these conditions.

At this time, the old lady decided to find you a flower. after some XXOO, you found that his grandmother was a gender! Therefore, you must correct the conditions. Hahaha

Reference:
The more conditions the database requires more work, just as the more moves you need, the more services the lady needs. So if you just need a climax, you may just have it after a crash. What kinds of poisonous dragons, ice and fire can be saved for two days... obviously, right. the premise is what services you actually need.


My idea is as follows:
If you are interested in Miss, let's talk about it:
If I look for a lady now, there are now 1000 for me to choose (so nice). If I want to find one ......
